Two signal-processing approaches for estimating a power systempsilas electromechanical mode-shape properties using time-synchronized phasor measurements are presented. The methods are termed the ldquocommunication methodrdquo and the ldquochannel matching method.rdquo The basic approach for each method is presented along with examples. A comparison is also made with the traditional Welch periodogram averaging approach. The examples include simulation results as well as measured data from the… CONTINUE READING
